Experts at NASA’s Jet Propulsion Laboratory (JPL) in the US transmitted ultra-high-definition video to Earth from a record distance of 31 million kilometers, approximately 80 times the distance between our planet and the Moon. According to the statement on the official website, the file was sent using a laser from the Psyche spacecraft. Web site Space Agency.
The hero of the 15-second video was a ginger cat named Taters, one of JPL employees. The video showed how the pet hunted the laser pointer’s point.
The video signal took 101 seconds to reach Earth before being received by the Hale Telescope at Caltech’s Palomar Observatory in San Diego and then transmitted over the broadband network to the Jet Propulsion Laboratory at 267 megabits per second.
According to NASA officials, the demonstration marked a historic milestone in the development of laser communications that will allow data to be transmitted from deep space 10 to 100 times faster than existing radio frequency systems.
“It sent the video faster than most broadband Internet connections, even though the transmission was millions of miles away. In fact, after receiving the file from the Palomar Observatory on Earth, it traveled over the network to the JPL office at a slower speed than it had previously traveled in space,” he said, responsible for the development of electronic receivers project manager Ryan Rogalin.
